Abstract

The temperature measuring elements are arranged at given spacings (A) along the measuring probe. The measuring elements are electronic temperature sensors (9) whose measured values can be directly read at the probe end. The probe may contain a housing (13) with an electronic temperature evaluating circuit (16), a display (17) and a battery (15). The measured temperatures can be simultaneously read on a corresponding number of displays. Alternately a single display may be used and the individual values can be recalled using push-button or rotary switches. The probe may consist of a metal tube which can consist of thread-connected sections, disengageable for easy transportation. The front section then carries a threaded cutting tip, a temperature sensor and a two-pole plug connector for electric transmission to the rear probe half.

Description

Title: Haystack temperature measuring probe for simultaneous temperature

ture measurement at different points along the probe.

Currently known haymeters, both simple and electronic with a temperature sensor in the probe tip, only one point or one Measure position at the same time. Only when the respective probe is manually transferred to another The temperature can also be determined there. It is thus not possible with the previously known measuring probes, with a single introduction the probe the temperature curve in the haystack along the entire length of the probe At the moment or at a later point in time as often as desired. This is of great disadvantage, since the probe must be constantly moved in order to change the temperature to be able to determine along the length of the probe.

As a result of the existing heat capacity of the temperature sensor must also always a certain time elapse for each measuring point, which is also what this method means is also time consuming.

In order to avoid these disadvantages, the innovation according to the invention on the entire length of the probe on several temperature measuring elements. A particular advantage It also shows who the measuring elements are designed as electronic measuring sensors which display their respective temperature independently at the end of the probe, or their temperature can be called up individually, so that at a glance, without to have to move the hay stick measuring probe constantly along the temperature curve the entire probe can be detected in the haystack.

LEe haystack measuring probe (1) according to the invention has, as shown in Fig.

1 and 2 preferably have the following structure: For resharpening Removable cutting tip (2), front probe half (3) which can be unscrewed for transport is, with a measuring sensor (4) and two-pin jack plug (5) for electrical Transfer to the rear half of the probe (6) by means of the two-pole Jack socket (7) and other sensors (8, 9, ...). At the end of the probe are are Display instruments (10, 11, 12, ...), digital or analog, for the individual Sensors (4, 8, 9, ...) associated temperature display in a shower (13) directly attached to the rear half of the probe (6) or to the handle (14) if this is not the case Is designed to be unscrewable. In the housing (13) are also power supply means Battery or accumulator (15), electronic temperature evaluation, teschaltung (16), digital or analog temperature display (17) housed.

A particularly battery-saving and structurally simple arrangement results, for example, from the fact that only a single display (17) and everyone Sensors (4, 8, 9, ...) assigned, a button (18, 19, 20, ...) or multi-pole Step rotary switch (21) etc. is used and only when the relevant one is actuated Button (18, 19, 20, ...) or step rotary switch (, 21) current flows and the display (17) can be read. Preferably, the display (17) is designed so that it can also be read in the dark, which can be achieved, for example, by additional lighting (22) or by using an L! D; Displays is given automatically.
